Hi, this is Sandra Henry-Stocker, author of the “Unix as a Second Language” blog on Network World.
In today’s Linux tip, we’re going to look at top – one of my favorite tools for examining performance on a Linux system. Want to pinpoint why your Linux system is running slowly? Top can shed a lot of light on that.
top provides stats on some of the most important performance measurements – allowing us to get an idea how busy our system is and why.
To start top, just type top in a terminal window. As you can see, I’ve already got it running and my display is updating every 4-5 seconds.
So, what might we want to focus on?
1. Which tasks are using up a lot of CPU time – they’ll be at on the top of the list we see displayed. On the left, you can see the process IDs and who is running them.
2. How many tasks are waiting on average to get access to the CPU. We see 5-, 10-, 15-minute averages. If an average = 0.05. we’d have a process waiting to be run 1/20th of the time. And, given the 3 stats, we can tell whether the system is getting busier or less busy.
3. We can also see how much memory is free
4. Whether significant swap space is being used
In addition, top shows us …
o How many tasks are being run overall
o And how long the system has been up
Type q to quit, top to start it up again
If you type top -u , you’ll limit the display to one particular user
Interactively, we can type:
z to highlight the top process (the one using the most CPU time)
c to display complete paths
k to kill a task (we’ll be prompted for the PID –and must have sufficient privilege)
Top is one of the best commands for getting a quick view of how a system’s performing and pinpointing why it’s slow.

Microsoft will continue to pressure businesses to adopt Office 365, said a pair of Gartner analysts, by barring all but subscribers from accessing Office 365’s online services.

The restriction will go into effect in about two-and-a-half years, said Gartner analysts Michael Silver and Stephen Kleynhans, who authored a for-clients-only report in April.

Their forecast was couched as an assumption that enterprises should build into their IT planning and budgeting. “By YE20 [year-end 2020], it [Microsoft] will announce that only Office 365 ProPlus will be supported for accessing Office 365 online services,” wrote Silver and Kleynhans. “Office traditional will not be supported.”

Office 365 ProPlus is the name of the locally-installed applications – Word, Excel, Outlook and the rest – that are a core component of an Office 365 subscription.

Apple on Tuesday released the second developer beta build of its upcoming operating system updates for its hardware lineup.

The second betas for watchOS 5, macOS Mojave, iOS 12, and tvOS 12 are available in the developer portal and as an over-the-air update for those who already have the beta installed.

Apple first announced the updates at its developer conference in early June, releasing the first beta shortly after the event ended.

A public beta program is scheduled to open up by the end of June. At that time, anyone who is willing to test and provide feedback to Apple about the preview software can sign up.

Some of the more notable improvements coming in iOS 12, which powers the iPhone and iPad, include speed and performance improvements across the board, and new tools to track just how much time a user spends on his or her device. Screen Time also lets users set time limits for specific apps or app categories, after which the user is locked out of the app until the following day.

Apple is expected to release its suite of software updates to consumers later this year, most likely in September.

If your PC doesn’t run Streaming Single Instructions Multiple Data (SIMD) Extensions 2, you apparently won’t be getting any more Win7 patches. At least, that’s what I infer from some clandestine Knowledge Base documentation changes made in the past few days.

Even though Microsoft says it’s supporting Win7 until January 14, 2020, if you have an older machine — including any Pentium III — you’ve been blocked, and there’s nothing you can do about it.

Here’s how it happened. Back in March, the Win7 Monthly Rollup, KB 4088875, included a warning about SSE2 problems:

A Stop error occurs on computers that don’t support Streaming Single Instructions Multiple Data (SIMD) Extensions 2 (SSE2).

I talked about the bugs in KB 4088875 — one of the buggiest Win7 patches in recent memory — shortly after it was released. At the time, the KB article said:

When it comes to technology, it’s often the smallest details that make the biggest impact.

Sure, splashy elements like Android’s split-screen mode and notification channels made for great new-release bullet points when they came along (in Android 7.0, Nougat and Android 8.0, Oreo, respectively) — but let’s be honest: How often does either actually affect your day-to-day life? If you’re like the vast majority of Android phone-owners, the answer is probably “pretty darn rarely.”

But then there’s something like Android’s system-wide sharing feature — a long-standing element of the operating system that’s all too easy to take for granted. It’s the thing that lets you select text in an email or a web page and then beam it directly into a note, text message, or document. It’s what lets you open an image in your phone’s camera app and then send it directly into an editing utility like Snapseed or a storage service like Dropbox. It’s what lets you save a page from your phone’s browser to a place like Pocket, Inbox, or Evernote with a couple quick taps.

For years, it was Android’s quiet killer feature — a subtle but significant point of differentiation, especially since Apple didn’t add something similar into iOS until 2014. These days, such a feature may seem like table stakes, but that doesn’t make it any less important to the overall user experience.

There aren’t that many opportunities to buy a 2-in-1 convertible laptop with a central twisting hinge these days, as 360-degree rotation has rather stolen this format’s thunder. But Fujitsu continues to support it, with the new Lifebook T938.

This is a solidly built machine that could survive in a bag without a protective sleeve, and it’s not too heavy at 1.3kg. The 13.3-inch screen sits in a relatively large bezel, as you’d expect in a laptop whose screen can be set to face outwards for use in tablet mode. But you might not want to consider holding this laptop in a hand or crook of an arm for very long, as that 1.3kg weight will soon take its toll. The touch-screen’s FHD (1,920 x 1,080) resolution delivers enough detail, and Fujitsu offers an anti-glare option.

The keyboard is beautifully springy, offering a little more resistance on the downward stroke than usual: I rather like that, although tastes vary. The enter key is double-width and double-height, and the arrow keys are nearly full size. Touch typing at normal speed was no problem at all. The touchpad is nicely responsive and has physical buttons.

The 13.3-inch Lifebook T938 has a central screen hinge, runs 8th-generation Intel Core processors and weighs 1.3kg.

The Lifebook T938 runs on Intel 8th generation Intel Core processors, my review sample being fitted with a Core i7-8650U, along with 16GB of RAM. There are also Core i5-8350U and Core i5-8250U options. SSD storage is available in 128GB, 256GB and 512GB capacities, in PCIe or SATA III format.

There are lots of security features. The wrist rest houses Fujitsu’s PalmSecure biometric system, which uses vein patterns for user authentication. There’s also a fingerprint reader on the screen section, catering for login when the screen is uppermost and the PalmSecure reader is covered. Even more security is provided by a smartcard slot on the laptop’s left edge.

Fujitsu caters for legacy as well as cutting-edge connections, and there is a good range here: a pair of USB 3 ports and a USB-C port sit alongside a full-size HDMI port and an old-fashioned VGA connector. All of these fit into the base fairly easily. Fujitsu has not found it so easy to fit in a full-size RJ-45 Ethernet connector, and so has opted for a pull-out/pop-out port, as on the Lifebook U938. It’s very clever, but might prove a bit flimsy in the long term. An SD card reader and a 3.5mm audio jack round things off. LTE mobile broadband is available as an option.

The battery is removable and a second internal cell provides enough juice to allow you to hot-swap a replacement battery without having to close down the system.

Everything fits together very well, and those legacy ports will certainly enhance this laptop’s appeal for some. Fujitsu fans who want a 13.3-inch convertible with 360-degree rotating screen and an 8th generation Intel Core processor should consider the Lifebook P728.

The price for my review unit has not been confirmed, but a Core i5-8250U version costs £1,276 (inc. VAT; £1,066.33 ex. VAT) online. My Core i7 unit will therefore be a premium-priced system.

Apple is set to pay AU$9 million in penalties after the Australian Federal Court found that it made false or misleading representations to customers on their warranty rights under Australian Consumer Law (ACL).

The case, initiated by the Australian Competition and Consumer Commission (ACCC) in April last year, concerned users of iPhones and iPads who complained about “error 53”, which bricked some devices after they updated their iOS.

Via its US website, customer service calls, and Apple Australia in-store staffers, the tech giant had then told at least 275 customers between February 2015 and February 2016 that they were ineligible to remedies if their phone or tablet had been repaired by a third-party store.

“The court declared the mere fact that an iPhone or iPad had been repaired by someone other than Apple did not, and could not, result in the consumer guarantees ceasing to apply, or the consumer’s right to a remedy being extinguished,” ACCC Commissioner Sarah Court said.

“If a product is faulty, customers are legally entitled to a repair or a replacement under the Australian Consumer Law, and sometimes even a refund. Apple’s representations led customers to believe they’d be denied a remedy for their faulty device because they used a third-party repairer.”

Apple has already reached out to compensate around 5,000 customers, also offering a court-enforceable undertaking to train staff on how to deal with warranty matters and ACL compliance, as well as updating the policies on its website.

It has also said it will provide new devices as replacements for iPhones and iPads that have suffered a major failure, rather than refurbished ones.

Prior to the decision, Federal Court judge Mark Moshinsky had referred Apple and the ACCC to mediation over the matter in November.

The case also followed the ACCC accepting a court-enforceable undertaking from Apple back in 2014, following an investigation into the iPhone maker’s consumer guarantees policies and practices, and representations about consumers’ rights under ACL.

Last month, Apple Sales New Zealand was similarly issued a warning by the Commerce Commission over “likely” breaching the Consumer Guarantees Act (CGA) by misleading consumers on their right to a replacement device.

Apple had misled consumers by telling them that products are only covered by consumer law for two years, New Zealand Commerce Commissioner Anna Rawlings said.

“They apply for a reasonable period,” Rawlings said. “What is reasonable depends on the nature of the goods, any statements made about the goods, and how the consumer, in fact, uses the goods.

“Although businesses may form a view about how long a product should generally last, they must assess each reported fault on its own merits. They should not base decisions solely on how long a consumer has owned a product. The reasonable lifespan of a product will depend very much on what the product is,” Rawlings added.
